External validation of a QSAR for the acute toxicity of halogenated aliphatic hydrocarbons

Open publisher page 23 citations

Abstract

Abstract The validation of the predictive capability of a quantitative structure-activity relationship (QSAR) is a significant step toward the construction of a reliable model. This point is discussed and illustrated with data for a class of halogenated aliphatic hydrocarbons. For this class of compounds, a QSAR concerning their acute toxicity toward rat was recently published. This QSAR is verified in this study by selecting and testing an external validation set comprising six compounds. The QSAR is also used for predicting the acute toxicity of 38 nontested members of this class.
